FIELD OF THE INVENTION

The present invention relates to methods and apparatus for surgical procedures.

BACKGROUND OF THE INVENTION

Tibial plateau leveling osteotomy (TPLO) procedures are well known in the veterinary art. Tibial plateau leveling osteotomy procedures are used to correct ruptured cranial cruciate ligaments for various animals, particularly canines. These procedures provide an alternative therapy to ligament repair procedures. Tibial plateau leveling osteotomy procedures have become the standard of care for medium and large canines.

When the canine ligament partially or fully ruptures, the tibial plateau leveling osteotomy procedure provides a way to correct this problem. A curvilinear cut is made to the upper portion of the tibia. This cut portion of the tibia is then rotated on the order of about 20-30 degrees to create a more level plane or surface on the top of the tibia upon which the femur can rest. The cut and repositioned portion of the tibia is then secured to the lower portion of the tibia.

There is a need for a TPLO bone plate provided with a new design that allows surgeons to secure to one or more tibial segments of an animal, as part of a tibial leveling osteotomy procedure for an animal. Also needed is a TPLO bone plate that offers a means for providing rotational stability, particularly means for providing additional rotational stability to the TPLO procedure. Also needed is a method of fracture or osteotomy repair in animals that allows securing of dissected soft tissue to the anatomic position where it was dissected, during the fracture or osteotomy repair.

BRIEF SUMMARY OF THE INVENTION

The present invention provides apparatus and methods for bone-tissue fixation (for example, bone-soft tissue fixation) in animals, particularly canines, using a TPLO plate having one or more suture eyelets/holes/slots provided within the body of the plate to allow the user (surgeon) to confer means for providing rotational stability to the joint or the bone, and to the final TPLO repair. The TPLO plate may be also employed, if necessary, to reattach tissue (bone or soft tissue, for example) to the plate at the anatomical location where the tissue was dissected. The suture eyelets/holes/slots may be provided in any number and at any location on the plate, for example, on the proximal region of the plate.

The TPLO plate of the present invention includes a body preferably formed of a metal and one or more suture eyelets (suture holes or slots) or other similar features which are incorporated into the shaft (for example, the proximal region) of the plate. The suture eyelets (holes) may have various shapes, forms and configurations and may be provided on or within a surface of the bone plate in any number, depending on the characteristics of the osteotomy or of the plate design. The suture eyelets preferably receive a flexible strand for fixation of tissue (bone or soft tissue) to the bone plate to improve the rotational stability of the bone or joint.

The present invention also provides a method of improving the rotational stability of a joint or bone, for example, of the knee or stifle during a TPLO procedure. The method comprises the steps of: (i) providing a TPLO plate that includes one or more suture eyelets/holes/openings/slots on or within the bone plate; (ii) fixating the TPLO plate to bone with fasteners such as screws; (iii) passing suture through one or more suture eyelets of the TPLO plate; and (iv) securing the suture to bone to improve the rotational stability of the bone/joint and the overall TPLO repair.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides TPLO bone plates having one or more suture eyelets on or within the plate, to allow the user (surgeon) to increase the rotational stability of the bone or joint and, optionally, to reattach the soft tissue to the plate at the anatomical location where the tissue was dissected.

The TPLO bone plates of the present invention are provided in various sizes, for example, 2.7 mm standard, 3.5 mm small, 3.5 mm standard, 3.5 mm broad, 4.5 mm standard, etc., accommodating correspondingly-sized screws. The TPLO bone plates are designed to accept various locking and non-locking low profile cortical screws. In an exemplary embodiment, each plate is provided with a suture hole located cranially on the proximal portion of the plate that accepts one flexible strand, for example a strand of #5 FiberWire® or FiberTape®. Each plate is provided with a surface cut demonstrating where a laser line for the osteotomy will be. All angles and radii for the proximal contour may be equal for each plate design. Some geometries between the 2.7 mm, 3.5 mm, 4.5 mm plates are slightly different.

The TPLO plates of the present invention may be provided as single devices and/or as part of kits incorporating additional instruments and devices. For example, the TPLO plates may be provided with additional components known for TPLO procedures, such as locking and non-locking screws, threaded drill guide, drill guide, graduated drill bit, screwdriver such as hexalobe screwdriver, QuickConnect driver such as hexalobe QuickConnect driver, all sized according to the particular dimensions of the TPLO plate to be employed with.

The present invention also provides a TPLO procedure that improves the rotational stability of the joint or bone. The method comprises the steps of: (i) providing a TPLO plate that includes one or more suture eyelets/holes/openings/slots/apertures on or within the bone plate; (ii) fixating the TPLO plate to bone with fasteners such as screws; (iii) passing suture through one or more suture eyelets of the TPLO plate; and (iv) tying the suture to bone to improve the rotational stability of the joint or bone.

An exemplary method of fixation of anatomical tissue during surgical applications by employing a TPLO plate that improves the rotational stability of the bone or joint or repair site (surgical site), and also allows reattachment of soft tissue to bone and to the plate, comprises the steps of: (i) providing a TPLO plate that includes one or more suture eyelets/holes/openings/slots/apertures on or within the bone plate; (ii) placing the TPLO plate on the bone and dissecting the adjacent soft tissue to allow the plate to fit; (iii) fixating the TPLO plate to bone with fasteners such as screws; (iv) passing suture around the bone and through the suture eyelets of the TPLO plate; (v) passing suture through the dissected soft tissue and through the suture eyelets of the TPLO plate; and (vi) tying the suture to improve the rotational stability of the bone/joint/repair site, and to secure the dissected soft tissue to the anatomical position/location where it was dissected.

Referring now to the drawings, where like elements are designated by like reference numerals, FIGS. 1-3 illustrate a TPLO plate 100 of the present invention provided with a plurality of suture eyelets 99 (openings/slots/holes/apertures 99) incorporated into the plate to allow soft tissue attachment to the plate. For exemplary purposes only, the TPLO plate 100 is illustrated and described below as a bone plate for providing improved rotational stability in osteotomies of an animal such as a canine, and attachment of dissected biceps and/or adjacent muscles. However, the invention has applicability to the fixation of other bones or bone segments of canines or of other animals, including the fixation of associated soft tissue to bones or bone segments.

As shown in FIG. 2, the TPLO plate 100 includes a rigid body 10 with a longitudinal axis 11, a transversal axis 13, a first surface 17 and a second bone-contacting surface 19. Body 10 is preferably formed of a metal such as titanium, titanium alloy, stainless steel, or other materials that possess mechanical and physical properties suitable for coupling bones together. Body 10 is also defined by a distal region 12 (shaft 12) surrounded by a distal edge 12 a and a proximal region 14 surrounded by a proximal edge 14 a.

The body 10 of the TPLO plate 100 is provided with a first plurality of through holes or openings 55 a, 55 b that receive corresponding screws or similar fixation devices 25 to secure the bone plate to bone. The fixation devices 25 may be screws, anchors, washers or any combination thereof for securing the bone plate to bone. The first plurality of openings 55 a, 55 b extend from the first surface 17 through the body 10 and to the bone-contacting surface 19, for accommodating at least one fixation device. Openings 55 a, 55 b may be provided in any number and may have similar or different perimeters. Openings 55 a, 55 b may be also optimally placed in the body 10 of the plate and at various angles with respect to transversal axis 13 of the plate 100. Additional small holes may be added within the body of the plate for the purpose of inserting k-wires to help keep the plate stable during the process of fixating the plate to the bone. Exemplary plate designs may incorporate a single suture hole with a diameter approximately double than that of the diameter of k-wire holes.

The first plurality of openings 55 a, 55 b includes a first set of holes 55 a located within the proximal region 14 and the distal region 12 and extending asymmetrically along the longitudinal axis 11 of the body 10, and a second set of holes 55 b located only within the distal region 12 and in asymmetry relative to the longitudinal axis 11 of the body 10.

At least one of the openings 55 a may include spherical bushings to allow variable angle-locking to be achieved by threading at least one tapered locking screw into the spherical bushings, as detailed below. The tapered head will expand the bushing, locking the screw to the plate. Non-locking screws may be also employed and can be placed in any opening 55 a. If polyaxial bushings is employed, the polyaxial bushings offer the surgeon the freedom to direct the fixation devices (for example, screws) within the anatomical template, based on the fracture pattern and bone quality for better fixation and to achieve a low profile polyaxial suture plate with any angulation, for example, a 60 degree angulation. The polyaxial bushings in each hole provide multi-directional locking or non-locking capability of the plate/screw construct to the bone. Drill guides can angulate the bushing to the desired screw trajectory.

Openings 55 a may be provided in any number and may have similar or different perimeters. In the exemplary embodiment shown in FIG. 2, openings 55 a are circular and have the same diameter, while openings 55 b are oval and have same shape and dimensions. Openings 55 a, 55 b may be also optimally placed in the body 10 of the bone plate and at various angles with respect to a transversal axis of the TPLO plate 100. Openings 55 a, 55 b are preferably arranged non-linearly with respect to the longitudinal axis 11, for the 3.5 mm broad plates and 4.5 standard plates. In addition, as and shown in FIG. 2, axis 11 a passing through both centers of openings 55 a located on proximal region 14 and disposed along edge 14 a is about parallel to the longitudinal axis 11 of the body of the plate 100.

As also shown in FIGS. 1-3, the TPLO plate 100 includes a second plurality of through holes or apertures including one or more suture eyelets 99 (suture holes or slots) which are disposed within the body 10 of the bone plate 100. Exemplary TPLO plate 100 includes one, two or three suture eyelets or holes 99.

The suture eyelets 99 preferably receive a flexible strand 70 (FIG. 3) to increase the rotational stability of the bone or joint. The suture eyelets may also help in the fixation of soft tissue 80 to the bone plate 100. For example, and if desired, suture eyelets 99 allow the user (surgeon) to reattach soft tissue 80 to the plate at the anatomical location where the tissue was dissected. The suture eyelets 99 may have various shapes, forms and configurations and may be provided on or within a surface of the bone plate 100 in any number, depending on the characteristics of the osteotomy or of the plate design.

Suture eyelets 99 may be recessed and they extend from the first surface 17 through the body 10 and to the bone-contacting surface 19, to accommodate at least one flexible strand attached to soft tissue to be reattached to the bone and to increase the rotational stability of the bone or joint. Although reference to the eyelets 99 will be made below as to the suture eyelets 99, the invention is not limited to this exemplary-only embodiment and contemplates eyelets for passing of any flexible strand, for example, suture, suture tape such as FiberTape®, suture chain such as FiberChain®, or a flexible material forming (or part of) a continuous loop/button construct provided with a button and a continuous loop attached to the button, among many others.

Suture eyelets 99 may be chamfered suture eyelets or provided with fillets. Suture eyelets 99 are provided within the body of the plate 100 to allow the user (surgeon) to pass one or more flexible strands (for example, one or more suture strands such as FiberWire® suture) after or before the plate is fixed to bone. In this manner, suture eyelets 99 allow the user (surgeon) to reattach soft tissue 80 to the plate at the anatomical location where the tissue was dissected and to also increase the rotational stability of the bone or joint. The suture eyelets 99 (holes/apertures/openings or chamfered suture eyelets 99) may have various shapes, forms and configurations and may be provided on or within a surface of the TPLO plate 100 in any number. The suture eyelets 99 preferably receive at least one flexible strand 70 for fixation of soft tissue 80 to the TPLO plate 100. One or more flexible strands may be passed through one suture eyelet. One flexible strand may be passed through one or more suture eyelets.

In an exemplary embodiment, the first plurality of openings 55 a have a first uniform diameter “D” (FIG. 2) and the second plurality of suture eyelets 99 have a second uniform diameter “d” (FIG. 2) which is smaller than the first diameter “D.” The first diameter “D” is preferably at least four times larger than the second diameter “d.”

According to another exemplary embodiment, the bone plate 100 of the present invention has one suture eyelet and two other small holes that are intended for passing k-wires or similar instruments to facilitate stability of the plate prior to fixation with screws. The holes of the plate for accommodating fixation devices (screws) preferably are provided asymmetrically relative to the longitudinal axis of the body of the plate. Other embodiments may also have only one oval hole or two oval holes that are centered on the longitudinal axis of the body of the plate.

The present invention also provides a suture plate kit (assembly) with a bone plate 100 (suture plate 100) of the present invention and a suturing kit including at least one flexible strand attached to at least one needle. The at least one flexible strand may be FiberWire® suture containing color coded suture, for example, a #2 and/or #5 FiberWire® sutures, with needles on each end, to facilitate suturing the soft tissue to the bone plate after the plate is in place. The needles may be attached to the suture by any method known in the art, for example, by being swedged onto the suture. FIG. 3 illustrates exemplary TPLO bone plate 100 of the present invention with tissue 80 to be attached to its proximal region 14 and with attached suture 70 to be passed through one of the suture eyelets 99 (the cranial proximal eyelet 99) for further attachment of soft tissue to TPLO plate 100.

The present invention also provides a method of forming a TPLO plate having suture holes for soft tissue attachment (or reattachment) for surgical application and for increasing the rotational stability of the joint or the bone. One to three suture eyelets 99 are formed within the body of a TPLO plate to enable a surgeon to easily place the tissue 80 to be attached/reattached back to the bone (for example, ligament or other soft tissue) during a TPLO procedure.

The present invention also provides a method of stabilizing a canine proximal tibia, comprising inter alia the steps of: (i) providing a TPLO plate having a body with a first surface, a second surface opposed to the first surface, the body having a proximal region and a distal region, a first plurality of apertures passing through the plate, the first plurality of apertures accommodating a plurality of fixation devices, a second plurality of apertures passing through the plate, the second plurality of apertures accommodating a plurality of flexible strands attached to soft tissue to be reattached to the bone; (ii) securing the TPLO plate to tibia by inserting the plurality of fixation devices at various angles relative to a transversal axis of the body; (iii) passing at least one flexible strand (for example, monofilament suture) through at least one of the second plurality of apertures; and (iv) securing the at least one flexible strand to femur or to soft tissue with a fixation point on the femur, to improve the rotation stability of canine bone or joint.
